Earlier quoted context omitted.
Heavily disagree. I own the server, thus the website. I should be able to allow or disallow any type of web crawler/scraper i want. Similar to how you cant easily regulate whats in a website without lawsuits and takedowns, you cant regulate how discoverable a website is.
> I should be able to allow or disallow any type of web crawler/scraper i want. You're certainly allowed to try, but I don't see why indexers should be mandated to collaborate with you. They serve their users, not you.
I mean, "allow" or "regulate" don't _really_ apply here - there was never any enforcement regime around robots.txt, just a convention based on the general expectation that you don't claim ownership of whatever passes your line of sight.
